You can easily integrate the Active Social Send Message Popup with Active Forums, other modules or even your own applications. Using the popup, allows the user to quickly send a private message to another member without leaving the current page. The image below is an example of how the Send Message Popup would appear within Active Forums.
The first thing you need to do is make sure you have at least one instance of Active Social anywhere on the page. In most cases you will have the Active Social Welcome Center or Message Center already on the page. You can easily create an empty custom view in the Active Social Control Panel under Design > Custom Views. Just add something a simple as the code below, then click save.
If you wish to use the Send Message Popup in Active Forums you will need to modify the ProfileInfo template. Below is a sample to get you started. Make sure you remove the spaces in the UserId token.
<a onclick="asClient.ShowSend([ AF:PROFILE:USERID ],this); return false;" title="Send Message">Send PMa>
The code example above can be used anywhere in your site where you can template or predefine the UserId as you see in the script sample above.
